[0010]
Here, as shown in FIG. 3, the heat insulation floor panel unit 1 on the western side is set to be slightly smaller than the square floor panel 2 and the vertical dimension of the floor panel 2, and is set on the back surface of the floor panel 2. More than a plurality of joists 3 arranged at intervals, a horizontal dimension corresponding to the distance between the inner surfaces of a pair of adjacent joists 3, 3, and a vertical dimension corresponding to the length of the joists 3, and the height of the joists 3. The floor panel 2 is formed in a thick plate shape having a slightly small height and is in contact with the opposing inner side surfaces of a pair of adjacent joists 3 and 3, respectively, and further in contact with the outer surface of one outermost joist 3 respectively. The total of the sum of the widths of the plurality of joists 3 and the sum of the widths of the plurality of hard heat insulators 4 is the width of the floor panel 2. It is set to approximately match the dimensions.
[0011]
Here, as the hard heat insulating material 4, for example, three types of polystyrene foams B are used, used as a strength member capable of supporting the floor panel 2, and supporting the load acting on the floor panel 2 together with the joists 3. Is something that can be done. Therefore, when the plate thickness of the floor panel 2 is constant, the span of the joist 3 for preventing the floor panel 2 from being bent can be increased as compared with the case where the hard heat insulating material is not used. The height of 3 can be lowered.
[0012]
On the other hand, the thermal floor panel unit 1A on the Japanese-style room side has the same size as the floor panel 2 of the thermal-insulated floor panel unit 1 on the Western-style room side, as shown in FIG. The floor panel 2 is attached to the back surface of the floor panel 2 in a space defined by the floor panel 2 and the plurality of joists 3A disposed at predetermined intervals on the back surface of the floor panel 2, and the floor panels 2 and the joists 3A. The hard heat insulating material 4A supports the load acting on the floor panel 2 in cooperation with the joist 3A.
[0013]
However, the height of the joist 3A of the heat insulation floor panel unit 1A on the Japanese-style room side is set lower than the height of the joist 3 of the heat insulation floor panel unit 1 on the western-room side, Cutout portions 3a, 3a are formed and are constructed on the base 16, the large pull 14, or the like. Further, the hard heat insulating material 4A also has the same side shape as the side shape of the joist 3A, that is, the same height as the joist 3A, and a notch 4a is formed at both ends of the lower surface.
[0014]
The height of the joist 3A and the hard heat insulating material 4A and the notches 3a and 4a of the heat insulating floor panel unit 1A on the Japanese-style room side are set in consideration of the ceiling height, the thickness of the tatami mats, and the like.
